SPECIFICATION forming part of Letters Patent No. 761,939, dated June 7, 1904.

Application filed September 18 1900 Be it known thatI, FRIEDRICH BOLEG,Cl1emist, of Bahnhofstrasse 1,Esslingen-on-Neckar,

'ui temberg, Germany, have invented a new 4 Process of Manufacturing Clear and Permanent Vatery Solutions of Mineral and Rosin Oils, of which the following is at full, 'clearg and exact description. i t a The object of my presentinvention is to pm- .f d uce clearand permanent watery solutions of mineral and rosin oils from the soluble or emulsitiable mixtures of mineral and rosin oils. In

producing these oils a suitable mineral oil is put into a washing-trough withacertain 'percent- 1 ageof. crude anhydrouslight colored rosin oil. and is then treated with-direct steam at about five, atmospheres pressure. 3 The n ixture isboiled at not morethan 100 to.105 Celsius.'

Then from five to seven per cent. of ca ustic-soda lye of 40 Baum is added, according to specific gravity. The mixture is maintained, for

' twenty or thirty minutes in a boiling state and treated until the oil is seen toclearly separate from the soap-lye. After allowing the whole to stand for threefourths ofan hour 1 the clear oil is drawn 011'.

In order to producethe said watery sollrtions, I proceed as follows; The OllS produced.

in the manner above referred to are intimately mixed in an oxidizing apparatus or in a press'urest1ll by means of air under pressure at to Celsius with about fifty, sixty-six and two-thirds, seventy-five (or less or more) .partsof distilled water. All mineraloils, the

light as well as the heavy, may be used. According as oils of a more or less specific gravity are used and according to the-quantity of water, I add to the-said mixture at the same time aquantity of suitably-prepared gelatinthat, is to say, one-eighth to onehalf per cent. dissolved in one hundred per cent.,, of vaterwhich is dissolved therein:

I The addition, of gelatin serves as a regulat mg agent of the desired viscos ty and has the ob ect to produce permanent solutions} In:

This process 3 is continued until the mixture becomes quite cleainor maintains itself clear in cooling it for trial on a glass plate, this operation enduring about forty-five to sixty minutes.

.is effected in a' pressure-still or distilling apparatus, it is subjected therein after having cut off the supplylof the compressed air to a pressure of .one to, one and one half atmosspeci'fic gravity than 0.900 and one and onefourth to one and one-half atmospheres in oils the specific gravity of which is greater than 0.900.) ,This operation is continued about during half an hour by heating the mixture by means of indirect steam. ,The permanency of clearnessof the solutions may be ascertained also in this case by coolingthem for trial on a glass plate before the apparatus is ,being put out of action.

The use of the second method. is preferable, because the watery-oil solutions produced undeinpressure have a greater permanency and resistance against heat as well as againstcold. This is also the reason for which the preferred to the troubled solutions and mixi tures or emulsions.

That I claim, and desire to secure by Let ters Patent. is
